How can it be that people still do not understand what the pyramids were, and are?
Pyramids weren't power plants per say, but people building it were batteries that brought it up and maintained it. When the era of pharaohs ended, the pyramids started to decay.
In today's perspective you could see pyramid in a way that you are a working inside of a it bringing power to the people on top of that pyramid. In times of Egypt, they were pharaohs and today they are someone else. In other words, pyramids today aren't a visibile structure that you can see or touch. You live inside of it as a slave.
By the way, Matrix wasn't a movie. It was a documentary that tried to tell you the truth.
